Contents of the invention

The problem to be solved by the invention

Sometimes, the pole plate is transported to the stacking section where a plurality of pole plates can be collected by the above-mentioned conveying device equipped with pinch rollers. Gather in the gathering department. An object to be transported, which is fragile and easily changes shape like an electrode plate, may be damaged by the impact when it hits the baffle or falls.

One aspect of the present invention provides a conveying device capable of suppressing damage to conveyed objects.

method used to solve the problem

A conveyance device according to one aspect of the present invention includes a conveyance unit and a prevention unit. The conveying unit conveys the object to be conveyed in a direction intersecting the extrusion direction of the object to be conveyed while extruding the object to be conveyed. The prevention part is arrange|positioned at the side which pushes out the object to be conveyed in the conveyance part. The preventing portion abuts against the object to be conveyed to prevent the object to be conveyed from being extruded. The transport unit has a pair of rotating bodies. The pair of rotating bodies includes a pair of rotating shafts and a pair of helical parts. The pair of rotating bodies extends along the conveyance direction of the object to be conveyed. The pair of helical parts are helically wound around the pair of rotating shafts. The pair of helices are wound in opposite directions to each other. The pair of helical parts supports the object to be conveyed in a pair of support regions between the pair of rotation shafts.

In the transport device according to one aspect of the present invention, the transport unit has a pair of rotating bodies. The pair of rotating bodies includes a pair of helical parts wound helically around the pair of rotating shafts. The pair of helices are wound in opposite directions to each other. The pair of helical parts supports the object to be conveyed in a pair of support regions between the pair of rotation shafts. Therefore, when the pair of rotating bodies rotates, the object to be conveyed is extruded while being supported by the pair of spiral parts. A stopper is arranged on the side where the object to be transported is extruded. Therefore, the object to be conveyed is conveyed along the prevention part while abutting against the prevention part in a state supported by the pair of screw parts. Therefore, it is possible to suppress damage to the object to be conveyed compared to a case where the object to be conveyed hits the baffle and falls without being supported.

The transport device according to one aspect of the present invention may further include a supply unit. The supply unit may supply the transport object to the transport unit from a side of the transport unit opposite to the blocking unit. In this case, the object to be transported can be easily supplied to the transport unit.

In the transport device according to one aspect of the present invention, each time the supply unit supplies the transport object to the transport unit, the pair of rotating bodies can make one rotation from the reference rotational position. In this case, it is possible to avoid interference between objects to be transported. Therefore, damage to the object to be transported can be further suppressed.

In the conveyance device according to one aspect of the present invention, the pair of end edges on the downstream side in the conveyance direction of the pair of spiral parts may be arranged outside the pair of support regions at the reference rotation position. In this case, the object to be conveyed can be fed out from the pair of spiral portions without being caught by the end edges on the downstream side in the conveying direction of the pair of spiral portions.

In the conveying device according to one aspect of the present invention, the pair of spiral parts may have a pair of supporting surfaces for supporting the object to be conveyed, and a pair of convex parts provided on peripheral edge parts of the pair of supporting surfaces. In this case, the convex portion abuts on the object to be conveyed to support the object to be conveyed. Therefore, the object to be conveyed can be conveyed while suppressing the friction between the object to be conveyed and the support surface due to the rotation of the rotating body.

In the conveying device according to one aspect of the present invention, the pair of spiral parts may have a pair of supporting surfaces for supporting the object to be conveyed, and a pair of convex parts provided on peripheral edge parts of the pair of supporting surfaces. In a pair of upstream side blade parts with a first pitch from the upstream side of the conveyance direction of the pair of helical parts at the reference rotation position, a pair of convex parts may be provided avoiding the intersecting area of the preventing part side intersecting The region is the region on the stopper side in the region where the trajectory of the front end of the object to be conveyed from the supply part to the stopper intersects the peripheral edge parts of the pair of support surfaces when viewed in the conveyance direction. In this case, the convex portion abuts on the object to be conveyed to support the object to be conveyed. Therefore, for example, by arranging the convex portion so that the convex portion abuts on the object to be conveyed, avoiding a portion where the object to be conveyed is easily damaged, damage to the object to be conveyed can be further suppressed. Moreover, the convex part is provided avoiding the area which tends to collide with the front end part of the object to be conveyed from the supply part toward the stopper part. Therefore, it is possible to suppress damage to the front end portion of the object to be transported by colliding with the convex portion.

In the conveyance device according to one aspect of the present invention, in the pair of upstream side blade portions at the reference rotation position, the pair of convex portions may be provided from a position where, when viewed from the conveyance direction, the distance from the reach stopper The region where the rear end of the object to be conveyed intersects the peripheral edge portions of the pair of support surfaces is located more upstream in the conveyance direction and is located more downstream in the conveyance direction than the intersecting region on the side of the stopper. In this case, when the object to be conveyed is supplied to the conveyance part and reaches the stopper, the object to be conveyed can be supported by the convex part. Therefore, the object to be conveyed can be conveyed while suppressing the friction between the object to be conveyed and the support surface due to the rotation of the rotating body.

In the conveying device according to one aspect of the present invention, the pair of protrusions may be provided up to a pair of end edges on the downstream side in the conveying direction of the pair of spirals. In this case, the object to be conveyed can be conveyed while further suppressing the friction between the object to be conveyed and the support surface due to the rotation of the rotating body.

In the conveying device according to one aspect of the present invention, the pair of spiral portions can be wound at equal pitches, and the pitch can be enlarged at the end edge on the upstream side in the conveying direction. In this case, even if the object to be conveyed supplied to the pair of augers comes into contact with the stopper and bounces up due to the reaction, the object to be conveyed can enter the inside of the auger from the inlet of the auger.

In the transport device according to one aspect of the present invention, the radii of the pair of spiral portions may be the same as each other. In this case, rotation control of the pair of helical portions becomes easy.

In the transport device according to one aspect of the present invention, the radii of the pair of spiral portions may be different from each other. In this case, the distances between the pair of rotation shafts and the stopper may be made different from each other according to the shape of the object to be conveyed.

In the conveying device according to one aspect of the present invention, the stopper may have: an opposing surface opposed to the conveying part; and a pair of guides provided on the opposing surface and extending along the conveying direction. In this case, the object to be conveyed can be guided by a pair of guides.

In the transport device according to one aspect of the present invention, the distance between the pair of guides may become narrower toward the downstream side in the transport direction. In this case, the object to be conveyed can be positioned in the opposing direction of the pair of guides while the object to be conveyed is conveyed.

In the transport device according to one aspect of the present invention, the pair of rotating bodies can rotate so that the linear speeds of the peripheral parts of the pair of spiral parts are equal to each other. In this case, the pair of spiral parts can straightly extrude the object to be conveyed toward the stopper part.

In the transport device according to one aspect of the present invention, the object to be transported may be an electrode plate. In this case, breakage of the electrode plate can be suppressed.

Detailed ways

Embodiments will be described in detail below with reference to the drawings. In the description of the drawings, the same symbols are used for the same or equivalent elements, and repeated descriptions are omitted.

FIG. 1 is a plan view showing a transport device according to the embodiment. Fig. 2 is a side view showing the transport device according to the embodiment. The conveying device 1 according to the embodiment shown in FIGS. 1 and 2 conveys the pole plate 2 for a lead acid battery as a conveyed object to be conveyed. The object to be transported by the transport device 1 is not limited to the electrode plate 2 . The conveying device 1 is applied, for example, to the accumulation process of the electrode plates 2 in a battery production line, and conveys the electrode plates 2 sequentially. The transported electrode plates are collected in the stacking unit 3 and then sent to the next process.

The electrode plate 2 is a substantially rectangular thin plate-shaped member. The electrode plate 2 has a pair of main surfaces facing each other in the thickness direction. The electrode plate 2 has a support made of lead alloy, an electrode material held by the support, and a current collector (ear) provided on the upper end of the support. A portion between the upper end portion and the lower end portion of the support body is formed in a lattice shape by, for example, expansion processing. The electrode material is formed by applying an electrode material paste to the grid-shaped portion of the support. The electrode material is easy to fall off from the support body, and in order to prevent the electrode material from falling off, paper is pasted on the surface of the electrode material. The upper end and the lower end of the support are exposed from the current collector. Therefore, a level difference is formed between the upper end portion and the lower end portion of the electrode plate 2 .

The transport device 1 includes a supply unit 4 , a transport unit 5 , and a prevention unit 6 arranged in this order. In FIG. 2 , illustration of a guide 9 described later in the stopper portion 6 is omitted.

The supply unit 4 is arranged on the opposite side of the transport unit 5 from the stopper 6 . The supply unit 4 supplies the electrode plate 2 to the transport unit 5 from the opposite side of the transport unit 5 to the stopper 6 . The supply unit 4 has a conveyor belt 4a and a rotary roller 4b. The conveyor belt 4 a conveys the electrode plate 2 toward the conveyance unit 5 . The conveyor belt 4 a is arranged such that the end portion on the downstream side in the conveying direction is higher than the end portion on the upstream side in the conveying direction, and conveys the electrode plate 2 obliquely upward. The rotating roller 4b is arranged between the conveyor belt 4a and the conveyance unit 5, and is adjacent to the downstream end of the conveyor belt 4a in the conveyance direction.

The upper surface of the rotary roller 4b is located substantially on the extension line of the upper surface of the conveyor belt 4a. Therefore, the electrode plate 2 conveyed by the conveyor belt 4a is smoothly transferred to the rotary roller 4b. The rotating roller 4 b rotates so that the upper surface side of the rotating roller 4 b advances toward the conveyance part 5 , accelerates the electrode plate 2 and sends it out to the conveyance part 5 . After the electrode plate 2 flies out from the supply part 4 obliquely upward, it falls in a parabola and is transferred to the conveying part 5 . Thus, the electrode plate 2 is supplied to the conveyance unit 5 .

The transport unit 5 is arranged between the supply unit 4 and the prevention unit 6 . The transport unit 5 transports the pole plate 2 in a direction intersecting the extrusion direction D1 of the pole plate 2 while extruding the pole plate 2 toward the stopper 6 . In the present embodiment, the transport unit 5 transports the electrode plate 2 downward (vertically downward) while extruding the electrode plate 2 in a substantially horizontal direction. That is, the extruding direction D1 of the electrode plate 2 in this embodiment is a substantially horizontal direction, which is a direction on the side of the stopper 6 of the transport unit 5 . The conveying direction D2 of the pole plate 2 is the downward direction.

The conveyance part 5 has the rotating bodies 10 and 20 arrange|positioned facing each other. The relative direction D3 of the rotary bodies 10 and 20 is a direction intersecting the extrusion direction D1 and the conveyance direction D2. The rotating bodies 10 and 20 are arranged so as to be able to support the electrode plate 2 supplied from the supply unit 4 from both sides in the opposing direction D3. The rotating bodies 10, 20 include rotating shafts 11, 21 extending in the transport direction D2. That is, the rotating bodies 10, 20 are arranged such that the axial direction of the rotating shafts 11, 21 is parallel to the conveyance direction D2.

Fig. 3 is a cross-sectional view showing a pair of rotating bodies. As shown in FIGS. 1 to 3 , the rotating bodies 10 and 20 include spiral portions 12 and 22 spirally wound around the rotating shafts 11 and 21 . The spiral parts 12, 22 are circular when viewed from above. The radii of the helical portions 12, 22 are the same as each other. The radius of the spiral portion 12 , 22 refers to the distance from the axis of the rotating shaft 11 , 21 to the peripheral edge of the spiral portion 12 , 22 as viewed from above.

The pair of rotating bodies 10 and 20 rotate so that the linear velocities of peripheral edge portions 13 a and 23 a described later are equal to each other. The rotary bodies 10, 20 rotate in opposite directions to each other. Viewed from above, the rotating body 10 rotates counterclockwise, and the rotating body 20 rotates clockwise. The rotators 10 and 20 are stopped, and the rotators 10 and 20 make one rotation (360° rotation) from the reference rotation position every time the supply unit 4 supplies the electrode plate 2 to the transport unit 5 . The transport unit 5 detects that the electrode plate 2 has been supplied from the supply unit 4 , for example, by a sensor (not shown).

The spiral parts 12 , 22 have support regions R1 , R2 for supporting the pole plate 2 between the rotation axes 11 , 21 . That is, the spiral parts 12 , 22 support the pole plate 2 in the supporting regions R1 , R2 between the rotating shafts 11 , 21 . The pole plate 2 is guided (controlled) via the rotation axes 11 , 21 and supported in the support regions R1 , R2 . Specifically, the support regions R1 and R2 are regions between the virtual plane F1 and the virtual plane F2 defined as follows. The virtual surface F1 is a virtual surface extending along the extrusion direction D1 and the conveyance direction D2 and in contact with the tip of the rotary shaft 11 on the side of the rotary shaft 21 . The virtual plane F2 is a virtual plane parallel to the virtual plane F1 and in contact with the tip of the rotary shaft 21 on the side of the rotary shaft 11 . When the rotary bodies 10 , 20 rotate, the support regions R1 , R2 advance from the supply part 4 toward the blocking part 6 . Consequently, the pole plate 2 supported by the support regions R1 , R2 is extruded towards the blocking portion 6 .

The spiral parts 12, 22 have end edges 12a, 22a on the upstream side in the conveyance direction D2 and end edges 12b, 22b on the downstream side in the conveyance direction D2. The end edges 12a, 22a are where the spiral starts. The end edges 12b, 22b are where the spiral ends. The spiral portion 12, 22 has a plurality of blade portions 12c, 22c. The several blade|wing part 12c, 22c is the part divided every 360 degrees from the edge 12a, 22a. The plurality of blade parts 12c, 22c are arranged along the conveyance direction D2. The spiral portions 12, 22 are wound at equal pitches (for example, 7 mm). At the end edges 12a, 22a, the pitch of the spirals 12, 22 is increased (for example, 18 mm). The pitch of the spiral parts 12, 22 means the distance between the blade parts 12c adjacent to each other in the conveyance direction D2 among the spiral parts 12, 22. That is, in the spiral part 12, 22, the inlet of a spiral expands.

The spiral portions 12, 22 are wound in opposite directions to each other. When viewed from above, the spiral portion 12 is wound clockwise from the end edge 12a toward the end edge 12b. The spiral portion 22 is wound counterclockwise from the end edge 22a toward the end edge 22b. That is, the direction in which the spiral portion 12 is wound from the end edge 12 a toward the end edge 12 b is opposite to the rotation direction of the rotating body 10 . The direction in which the spiral portion 22 is wound from the end edge 22a toward the end edge 22b is the direction opposite to the rotation direction of the rotating body 20 . When the rotors 10 and 20 rotate, the electrode plate 2 supported by the spiral parts 12 and 22 is conveyed downward while sliding on the spiral parts 12 and 22 .

In the reference rotational position, the end edges 12a, 22a are arranged outside the supporting regions R1, R2. Specifically, at the reference rotation position, the edge 12a is arranged on the opposite side of the virtual plane F1 to the virtual plane F2. In the reference rotation position, the edge 22a is arranged on the side opposite to the virtual plane F1 of the virtual plane F2. In the reference rotational position, the end edges 12a, 22a are outside the support regions R1, R2 and substantially parallel to the relative direction D3.

In the reference rotation position, the end edges 12b, 22b are arranged outside the supporting regions R1, R2. Specifically, at the reference rotation position, the edge 12b is arranged on the opposite side of the virtual plane F1 to the virtual plane F2. In the reference rotation position, the edge 22b is arranged on the side opposite to the virtual surface F1 of the virtual surface F2. In the reference rotation position, the end edges 12b, 22b are on the side of the stopper 6 of the rotation shafts 11, 21 and are substantially parallel to the extrusion direction D1.

The helix 12 , 22 has a support surface 13 , 23 and a protrusion 14 , 24 . The support surfaces 13 , 23 are opposite to the main surface of the pole plate 2 and support the pole plate 2 . The convex parts 14 and 24 are provided on the peripheral edge parts 13 a and 23 a of the supporting surfaces 13 and 23 . The protrusions 14 and 24 have a rectangular cross section, for example. The width of the protrusions 14 and 24 is, for example, 5 mm. The height of the protrusions 14 and 24 is, for example, 3 mm. At the reference rotation position, the pole plate 2 is fed onto the blades 12c, 22c (upstream side blades) at the first pitch from the upstream side of the spirals 12, 22 in the transport direction D2.

FIG. 4 is a plan view for explaining a region where a convex portion is provided. In FIG. 4 , the illustration of the supply unit 4 (see FIG. 1 ) is omitted. As shown in FIG. 4 , in the blade portions 12 c , 22 c at the first pitch at the reference rotational position, the convex portions 14 , 24 are provided avoiding regions R3 , R4 (blocking portion side intersection regions). The regions R3 and R4 are regions on the stopper portion 6 side among the four regions where the pair of tracks L intersect the peripheral edge portions 13a and 23a. The pair of trajectories L are trajectories along which the pair of front end portions 2 a of the electrode plate 2 travel from the supply unit 4 to the stopper unit 6 as viewed from the transport direction D2 . The front end portion 2 a refers to an end portion on one side of the front end of the electrode plate 2 . Regions R3 and R4 are regions in which the convex parts 14 and 24 are likely to collide with the pair of front end parts 2 a of the electrode plate 2 going from the supply part 4 to the stopper part 6 .

In the blade portions 12c, 22c of the first pitch at the reference rotational position, the convex portions 14, 24 are provided such that they are located on the upstream side in the transport direction D2 from the regions R5, R6, and from the regions R3, R4 starts from the position on the downstream side of the conveyance direction D2 to the edge 12b, 22b (refer FIG. 1). Regarding the regions R5 and R6, the rear end of the electrode plate 2 reaching the stopper 6 intersects the peripheral edge portions 13a and 23a as viewed from the conveyance direction D2. That is, the starting positions of the protrusions 14, 24 are different from the end edges 12a, 22a. That is, it is located on the upstream side of the conveyance direction D2 rather than the regions R5 and R6 , and is located on the downstream side of the conveyance direction D2 than the regions R3 and R4 . In other words, the starting positions of the protrusions 14 , 24 are closer to the front side in the extrusion direction D1 than the regions R5 , R6 , and closer to the rear side in the extrusion direction D1 than the regions R3 , R4 . In other words, the starting position of the convex portion 14 is closer to the front side in the rotation direction of the rotor 10 than to the region R5 and to the rear side in the rotation direction of the rotor 10 than to the region R3 . The starting position of the convex portion 24 is closer to the front side in the rotation direction of the rotor 20 than to the region R6 and to the rear side in the rotation direction of the rotor 20 than to the region R4 . The end positions of the protrusions 14, 24 are the end edges 12b, 22b. Therefore, the pole plate 2 maintains the state supported by the protrusions 14 , 24 from when the pole plate 2 is supplied to the transport unit 5 and reaches the stopper 6 until the transport of the pole plate 2 by the transport unit 5 is completed.

As a material of the spiral parts 12 and 22, for example, aluminum (A5052) can be used. Aluminum is less prone to corrosion than iron. Since aluminum is lighter than stainless steel, it can suppress the load on the engine. Aluminum has higher wear resistance than resin.

Fig. 5 is a front view showing a stacking section, a rotating body, and a blocking section when viewed from the supply section side. As shown in FIG. 1 , FIG. 2 and FIG. 5 , the preventing part 6 is arranged on the side of the conveying part 5 where the pole plate 2 is extruded. The preventing part 6 abuts against the front end of the electrode plate 2 in the extrusion direction D1 to prevent the electrode plate 2 from being extruded from the conveying part 5 . The blocking part 6 has a back plate 7 and guides 8 , 9 .

The back plate 7 has a facing surface 7 a facing the conveyance unit 5 . The opposing surface 7a has a substantially rectangular shape. The facing surface 7 a is in contact with the electrode plate 2 , and the position of the tip of the electrode plate 2 in the extrusion direction D1 is appropriately determined. The guides 8, 9 are provided on the facing surface 7a facing each other in the facing direction D3, and extend along the conveyance direction D2. The guides 8, 9 have guide faces 8a, 9a facing each other in the opposing direction D3. The distance between the guide surfaces 8a, 9a becomes narrower toward the downstream side in the conveyance direction D2. The distance between the guide surfaces 8 a and 9 a at one end on the downstream side in the transport direction D2 corresponds to the width of the electrode plate 2 . The guide surfaces 8a, 9a appropriately determine the position of the pole plate 2 in the opposing direction D3.

Immediately below the transport unit 5, a stacking unit 3 capable of stacking a plurality of electrode plates 2 is arranged. The accumulation part 3 accumulates the electrode plate 2 conveyed and dropped by the conveyance part 5. The gathering part 3 has a lifting function. Whenever the pole plate 2 is transported, the gathering part 3 is only lowered by the thickness of the pole plate 2 . Thereby, the falling distance of the electrode plate 2 can be kept constant. The drop distance of the electrode plate 2 is set to be less than or equal to 30 mm, for example. If a predetermined number of pole plates 2 are gathered in the gathering section 3, the gathered pole plates 2 are sent to the next process. After sending out the electrode plates 2 , the stacking unit 3 raises only the thickness of the predetermined number of sent out electrode plates 2 , and repeats the process of collecting the electrode plates 2 transported by the transport unit 5 .

In the transfer device 1 configured as above, the electrode plate 2 is first supplied to the transfer unit 5 by the supply unit 4 . In the transport unit 5 , the electrode plate 2 is supplied between the rotating shafts 11 , 21 of the rotating bodies 10 , 20 . At this time, the rotating bodies 10 and 20 are in a stopped state at the reference rotating position. When the electrode plate 2 is supplied, the rotating bodies 10 and 20 make one rotation from the reference rotation position. As a result, the pole plate 2 is extruded toward the stopper 6 . The convex portions 14, 24 are provided avoiding the regions R3, R4. In the regions R3 , R4 , the convex portions 14 , 24 are likely to collide with the pair of front edge end portions 2 a of the electrode plate 2 going from the supply portion 4 to the stop portion 6 . Therefore, the pair of front edge end portions 2 a of the electrode plate 2 reach the stopper portion 6 without colliding with the convex portions 14 , 24 . After the rotary bodies 10 and 20 have rotated once, they are in the state of stopping at the reference rotation position again.

The pole plate 2 is conveyed downward while sliding on the supporting surfaces 13 and 23 in a state of being in contact with the stopper 6, and enters the inside of the spiral from the entrance of the spiral. When the next pole plate 2 is transported to the transport unit 5 , the rotating bodies 10 and 20 make another one revolution. As a result, the electrode plate 2 is sequentially conveyed downward along the support surfaces 13 and 23 in a state of being in contact with the stopper 6 . That is, the pole plate 2 is conveyed downward in a state where the front end of the pole plate 2 in the extrusion direction D1 is positioned. Then, the pole plate 2 is guided (controlled) by the guide surfaces 8a, 9a, and positioned in the opposite direction D3. In the reference rotation position, the end edges 12b, 22b are disposed outside the rotation shafts 11, 21 . Therefore, the pole plate 2 does not catch on the edge 12b, 22b and fall downward while reaching the edge 12b, 22b, and accumulates in the accumulation part 3. Thereby, the electrode plate 2 is conveyed to the stacking part 3, and the assembled body of the electrode plate 2 in which the position of the front-end|tip in the extrusion direction D1 and the position of the opposing direction D3 are aligned can be obtained.

As described above, in the conveying device 1 , the conveying unit 5 has the rotating bodies 10 , 20 including the rotating shafts 11 , 21 and the screw portions 12 , 22 . The spiral portions 12 , 22 are wound in opposite directions to support the pole plate 2 in the support regions R1 , R2 . Therefore, when the rotating bodies 10 and 20 rotate in opposite directions, the pole plate 2 is extruded while being supported by the support regions R1 and R2. A stopper 6 is arranged on the side where the electrode plate 2 is extruded. Therefore, the electrode plate 2 is conveyed downward along the opposing surface 7 a while abutting against the opposing surface 7 a of the stopper portion 6 in a state supported by the supporting regions R1 and R2 . Therefore, the damage of the pole plate 2 can be suppressed compared with the case where the pole plate 2 hits the baffle and falls without support.

The transport device 1 includes a supply unit 4 that supplies the electrode plate 2 to the transport unit 5 from the side of the transport unit 5 opposite to the stopper 6 . Therefore, the electrode plate 2 can be easily supplied to the conveyance part 5 .

Every time the supply unit 4 supplies the electrode plate 2 to the conveyance unit 5 , the rotating bodies 10 and 20 make one rotation from the reference rotation position. Thereby, interference of the pole plates 2 can be avoided. Therefore, damage to the electrode plate 2 can be further suppressed.

In the reference rotation position, the end edges 12b, 22b are arranged outside the supporting regions R1, R2. Therefore, the electrode plate 2 can be sent out from the pair of spiral parts 12, 22 without being caught in the end edges 12b, 22b.

The spiral parts 12 and 22 have convex parts 14 and 24 provided on the supporting surfaces 13 and 23 . Therefore, the protrusions 14 and 24 contact the pole plate 2 to support the pole plate 2 . Therefore, for example, if the protrusions 14 , 24 are arranged so that the protrusions 14 , 24 come into contact with the pole plate 2 while avoiding the easily damaged portion of the pole plate 2 , damage to the pole plate 2 can be further suppressed. In this embodiment, steps are formed between the upper end and the lower end of the pole plate 2 as described above. In this step portion, the paper covering the electrode material tends to be peeled off and damaged due to friction with the supporting surfaces 13 and 23 . In particular, where the support surfaces 13 and 23 are rubbed in the direction across the level difference, peeling and damage of the paper tend to occur. Therefore, such a place may be avoided, and the convex portions 14 , 24 may be arranged so that the convex portions 14 , 24 come into contact with the electrode plate 2 .

In the blade portions 12c, 22c at the first pitch at the reference rotational position, the convex portions 14, 24 are provided avoiding the regions R3, R4. In the regions R3 , R4 , the convex portions 14 , 24 are likely to collide with the pair of front edge end portions 2 a of the electrode plate 2 going from the supply portion 4 to the stop portion 6 . Therefore, it is possible to prevent the pair of front end portions 2 a of the electrode plate 2 from colliding with the convex portions 14 and 24 to be damaged.

In the blade portions 12c, 22c of the first pitch at the reference rotational position, the convex portions 14, 24 are provided from a position that is more upstream in the conveyance direction D2 than the regions R5, R6 and that is R3 and R4 are located on the downstream side of the conveyance direction D2. Therefore, when the electrode plate 2 is supplied to the conveyance part 5 and reaches the stopper part 6, the electrode plate 2 can be supported by the convex part 14,24. Therefore, the pole plate 2 can be transported while suppressing the friction between the pole plate 2 and the support surface 13 caused by the rotation of the rotating bodies 10 and 20 . Therefore, peeling and breakage of the paper covering the electrode material of the electrode plate 2 can be further suppressed.

The protrusions 14, 24 are provided up to the end edges 12b, 22b. That is, from when the pole plate 2 is supplied to the transport unit 5 and reaches the stopper 6 until the transport of the pole plate 2 by the transport unit 5 is completed, the pole plate 2 maintains the state supported by the protrusions 14 , 24 . Therefore, the pole plate 2 can be transported while further suppressing the friction between the pole plate 2 and the support surface 13 caused by the rotation of the rotating bodies 10 and 20 . Therefore, peeling and breakage of the paper covering the electrode material of the electrode plate 2 can be further suppressed.

The helical portions 12, 22 are wound at equal pitches, and the pitch is enlarged at the end edges 12a, 22a. Therefore, even if the electrode plate 2 supplied to the spiral parts 12 and 22 comes into contact with the stopper part 6 and bounces up due to the reaction, the electrode plate 2 can enter the inside of the spiral from the entrance of the spiral.

The radii of the helical portions 12, 22 are the same as each other. Therefore, rotation control of the spiral parts 12 and 22 becomes easy. The rotary bodies 10, 20 rotate so that the linear velocities of the peripheral edge portions 13a, 23a are equal to each other. Therefore, the spiral parts 12 and 22 can straightly extrude the electrode plate 2 toward the stopper part 6 .

The blocking part 6 has guides 8 , 9 . Therefore, the pole plate 2 can be guided by the guides 8 , 9 . The guides 8, 9 have guide surfaces 8a, 9a whose intervals become narrower toward the downstream side in the conveyance direction D2. Therefore, it is possible to position the electrode plate 2 in the opposing direction of the guide surfaces 8 a and 9 a while conveying the electrode plate 2 .

The present invention is not limited to the above-mentioned embodiments.

For example, the radii of the spiral portions 12, 22 may also be different from each other. The radii of the spiral parts 12 and 22 will be described using FIGS. 6 to 8 . FIG. 6 is a plan view for explaining the radius of the spiral portion according to the embodiment. FIG. 7 is a plan view for explaining the radius of the spiral portion according to the first modification. FIG. 8 is a plan view for explaining the radius of the spiral portion according to the second modification. In FIGS. 6 to 8 , the supply unit 4 (see FIG. 1 ) is omitted from illustration.

In the transport device 1 according to the embodiment shown in FIG. 6 , the radii of the spiral portions 12 and 22 are equal to each other. On the other hand, in the transport device 1A according to the first modification shown in FIG. 7 , the radii of the spiral portions 12 and 22 are different from each other. Specifically, in the transport device 1A, the radius of the spiral portion 12 is shorter than the radius of the spiral portion 22 . The pole plate 2A transported by the transport apparatus 1A is different from the shape of the pole plate 2 in that its lower end is cut off. Therefore, in the transport device 1A, the guide 8 disposed on the lower end side of the pole plate 2A is formed thicker than the guide 9 so as to be able to contact the uncut portion of the lower end of the pole plate 2A. Along with this, the radius of the spiral portion 12 is shorter than the radius of the spiral portion 22 .

In the transport device 1B according to the second modified example shown in FIG. 8 , the radii of the spiral parts 12 and 22 are also different from each other. Specifically, in the transport device 1B, the radius of the spiral portion 12 is shorter than the radius of the spiral portion 22 . The radius of the spiral portion 12 in the conveying device 1B is shorter than that of the spiral portion 12 in the conveying device 1A. The pole plate 2B transported by the transport apparatus 1B is different from the shape of the pole plate 2 in that the shape of the pole plate 2B is cut off at the lower end similarly to the shape of the pole plate 2A. Therefore, in the transport device 1B, similarly to the transport device 1A, the guide 8 disposed on the lower end side of the electrode plate 2B is formed thicker than the guide 9 so as not to be cut off from the lower end of the electrode plate 2B. part of the abutment. Along with this, the radius of the spiral portion 12 is shorter than the radius of the spiral portion 22 . Furthermore, the shape of the electrode plate 2B is also different from the shape of the electrode plate 2 in that the length in the extrusion direction D1 is short. Therefore, in the transport device 1B, the rotation shaft 11 arranged on the lower end side of the pole plate 2B is arranged on the side of the stopper 6 than the rotation shaft 21 so as to be able to guide the lower end portion of the pole plate 2B that is not cut off. part. Along with this, the radius of the spiral portion 12 is shorter than the radius of the spiral portion 22 .

In this manner, the radii of the spiral portions 12 and 22 are different from each other in the conveyance device 1A and the conveyance device 1B. Therefore, the distances between the spiral portions 12 , 22 and the stopper portion 6 (specifically, the guides 8 , 9 ) can be made different from each other according to the shapes of the pole plate 2A and the pole plate 2B. In the transportation device 1A and the transportation device 1B, the rotational speeds (angular velocities) of the rotating bodies 10 and 20 are made different from each other so that the linear velocities of the peripheral parts 13 a and 23 a (see FIG. 3 ) are equal to each other.

The conveying device 1 may not include the supply unit 4 and supply the electrode plate 2 using an external device. In this case, the configuration of the transport device 1 can be simplified. The spiral parts 12 and 22 may not have the convex parts 14 and 24 . The spiral parts 12 and 22 may be wound at equal pitches as a whole. In these cases, manufacture of the spiral parts 12, 22 becomes easy. In the embodiment, each time the supply unit 4 supplies the electrode plate 2 to the conveyance unit 5, the rotors 10 and 20 make one rotation from the reference rotation position, but the present invention is not limited thereto, and may rotate more than one rotation. The rotation of the rotating bodies 10, 20 may also be continuous rather than intermittent. The linear velocities of the peripheral portions 13a and 23a (see FIG. 3 ) may be different from each other. The stopper 6 may not have the guides 8 , 9 .
